I just checked. That person has 0 following count, 0 tweets. As i said before, if that person is Mark, then he’ll come out sooner or later. For now let’s keep this info for ourselves because there’s a reason why he had his twitter protected before. On a sidenote, I don’t think there’s any rule that idols can’t have twitter. Infact it helps them gain publicity or fans. I feel like there are personal reasons for this like Mark’s too busy, no time for social media or because his tweets are personal. Besides we know how Mark is, he’s very reserved and shy (and cute omfg..). So that probably explains for him having a personal twitter or no twitter at all. Again, for now let’s just keep it to ourselves for now and not disturb that person. [sorry for the long rant]
